Description

Technical Field

[0001] This application relates to the field of induction hardening processing, and in particular to a tooth surface heating and cooling device and system. Background Technology

[0002] In the field of mechanical manufacturing, meshing components such as gears or gear rings are key transmission parts, and their performance directly affects the operating efficiency and reliability of the entire mechanical equipment. Induction hardening is a heat treatment process widely used to improve the surface hardness and wear resistance of meshing components. By rapidly heating and cooling the tooth surface of the meshing components, a hardened layer is formed on the tooth surface, thereby improving the overall performance of the meshing components.

[0003] In existing technologies, when induction hardening meshing parts, the common method is to heat and cool each tooth individually. However, when the induction head heats the current tooth of the meshing part, the narrow width of a single tooth easily leads to heat transfer to adjacent teeth, causing them to overheat and resulting in over-tempering. Over-tempering reduces the surface hardness and durability of the meshing part's tooth surface, affecting its performance and service life. Summary of the Invention

[0004] In view of this, the present invention provides a tooth surface heating and cooling device and system, which can effectively reduce the temperature of adjacent teeth, prevent heat from accumulating on adjacent teeth, and avoid excessive tempering caused by excessive temperature.

[0005] In a first aspect, this utility model provides a tooth surface heating and cooling device for heating and cooling meshing parts. The meshing parts have a plurality of teeth and a tooth groove to be processed. The tooth groove has a groove wall surface, and two teeth adjacent to the tooth groove to be processed in the meshing parts have tooth back surfaces that are opposite to the tooth groove to be processed. The top surface of the teeth is a tooth tip surface. The tooth surface heating and cooling device includes:

[0006] frame;

[0007] A heating element is provided on the frame, and the heating element is adapted to be placed in the tooth groove to be processed and to heat the tooth groove wall surface;

[0008] Multiple cooling components are adjustablely mounted on the frame and located on opposite sides of the heating component. Each cooling component includes a nozzle with several spray holes. The nozzle sprays a cooling medium toward the top surface and / or back surface of the gear teeth through the spray holes.

[0009] Beneficial effects: this tooth surface heating and cooling device, when the meshing piece is quenched and heated, the heating piece is arranged in a single to-be-processed tooth groove of the meshing piece, the tooth groove wall surface of the gear tooth is heated by the heating piece, the heat is concentrated on the tooth groove wall surface to be processed, and the heat transfer to the adjacent gear tooth is reduced. At the same time, when the heating piece heats the current tooth groove wall surface, the heat has a tendency to spread to the adjacent gear tooth. Since the plurality of cooling pieces are respectively located on both sides of the heating piece, the nozzles on the cooling pieces spray the cooling medium towards the addendum surface and the dedendum surface of the gear tooth through the spray holes, or only towards the addendum surface or the dedendum surface of the gear tooth, effectively reducing the temperature of the adjacent gear tooth, preventing heat accumulation on the adjacent gear tooth, and avoiding excessive tempering phenomenon caused by excessive temperature. Ensure that the hardness and durability of the tooth surface of the meshing piece meet the requirements, improve the overall quality and performance of the meshing piece, and prolong the service life of the meshing piece.

[0010] In addition, since the plurality of cooling pieces are adjustably mounted on the rack, the cooling pieces can adapt to meshing pieces of different sizes and shapes. The operator can adjust the position or angle of the cooling piece according to the characteristics of the specific meshing piece, so that the spray holes of the nozzles can accurately spray the cooling medium to the addendum surface and / or the dedendum surface, achieving uniform and effective cooling, avoiding tooth surface soft spots or other defects of the meshing piece caused by uneven cooling, and further ensuring the heat treatment effect and reliability of the meshing piece.

[0011] In summary, the tooth surface heating and cooling device can effectively avoid excessive temperature of the adjacent gear tooth, thereby preventing excessive tempering phenomenon, and improve the performance and service life of the meshing piece.

[0012] In an alternative embodiment, the nozzle is provided with a first spray surface and a second spray surface corresponding to the addendum surface and the dedendum surface of the gear tooth, respectively. The first spray surface and the second spray surface are arranged at an angle, and a plurality of spray holes are arranged on the first spray surface and the second spray surface.

[0013] Beneficial effects: by arranging the first spray surface and the second spray surface on the nozzle, and making the first spray surface and the second spray surface correspond to the addendum surface and the dedendum surface of the gear tooth respectively, direct and comprehensive cooling of the two key parts of the gear tooth can be ensured. While the heating piece heats the to-be-processed tooth groove, the first spray surface and the second spray surface can simultaneously spray the cooling medium to the addendum surface and the dedendum surface, thereby cooling the addendum surface and the dedendum surface of the gear tooth top, effectively reducing the temperature of the adjacent gear tooth, preventing heat accumulation on the adjacent gear tooth, and thus obtaining the same hardness and strength from the root to the top of the gear tooth.

[0014] In addition, the first spray surface and the second spray surface are arranged at an angle, so that the spraying direction of the cooling medium can be diversified. Compared with single plane spraying, multi-angle spraying can make the cooling medium better cover the tooth top surface and the tooth back surface, reduce the cooling dead angle, improve the uniformity of cooling, help prevent tooth surface hardness differences, deformation and other problems caused by uneven cooling, and ensure the quality and performance stability of the meshing part.

[0015] In an optional embodiment, the width of the first spray surface is b1, and the width of the tooth top surface of the gear tooth is b2, and b1 < b2 is satisfied, so that the first spray surface sprays the cooling medium towards the side of the tooth top surface away from the tooth groove wall surface.

[0016] Beneficial effect: since the width b1 of the first spray surface is less than the width b2 of the tooth top surface, and the first spray surface sprays the cooling medium towards the side of the tooth top surface away from the tooth groove wall surface, the first spray surface can effectively reduce the temperature of the tooth top surface when spraying the cooling medium on the tooth top surface, while preventing the cooling medium from splashing onto the tooth groove wall surface during spraying, thereby reducing the heating temperature of the tooth groove wall surface and causing the hardness of the tooth groove wall surface to decrease.

[0017] During the heating process, the tooth groove wall surface needs to reach a certain temperature to achieve effective quenching of the gear tooth. If the cooling medium excessively affects the tooth groove wall surface, it will interfere with the heating effect, resulting in uneven heating or failure to reach the expected quenching temperature.

[0018] In an optional embodiment, along the height direction of the tooth surface heating and cooling device, the height of the nozzle is greater than or equal to 2 / 3 of the height of the heating part.

[0019] Beneficial effect: the height of the nozzle is greater than or equal to 2 / 3 of the height of the heating part, so that the cooling medium can cool the gear tooth in a larger height range. During the heating process, due to the influence of the height of the heating part, heat will be transferred and accumulated at different height positions of the gear tooth. A higher nozzle can ensure that the cooling medium covers more heated areas, effectively reducing the temperature of each part of the gear tooth, especially for the heat dissipation at higher positions of the tooth top surface and the tooth back surface, preventing problems such as excessive tempering or uneven hardness caused by local high temperature, thereby improving the overall heat treatment quality of the meshing part.

[0020] If the height of the nozzle is less than 2 / 3 of the height of the heating part, during the heating process, due to the influence of the height of the heating part, heat will be transferred and accumulated at each part of the gear tooth. Due to the small height of the nozzle, the cooling medium cannot effectively cover a large area of the gear tooth, resulting in that the heat in some areas of the gear tooth cannot be removed in time, causing insufficient cooling of the gear tooth. This may cause uneven hardness at different height positions of the gear tooth, affecting the overall mechanical properties and service life of the meshing part.

[0021] In an alternative embodiment, the cooling member further comprises a connecting pipe, and the nozzle is provided with a pipe joint, and the nozzle is communicated with the connecting pipe through the pipe joint.

[0022] Beneficial effects: By setting the connecting pipe in communication with the nozzle, the connecting pipe provides a stable transmission channel for the cooling medium, which can continuously transport the cooling medium from the outside to the nozzle and spray it out of the spray holes of the nozzle.

[0023] Since the nozzle is provided with a pipe joint, the nozzle is communicated with the connecting pipe through the pipe joint, so as to facilitate the connection of the connecting pipe with the nozzle, while ensuring smooth flow of the cooling medium during transportation to the nozzle, avoiding leakage and other problems, so that the cooling member can continuously and effectively cool the gear teeth.

[0024] When the nozzle is blocked, damaged or needs to be replaced with different types of nozzles according to different cooling requirements, the connection mode of the pipe joint makes the disassembly and installation of the nozzle relatively simple. The operator can quickly separate the old nozzle from the connecting pipe and install a new nozzle, reducing maintenance cost and time.

[0025] In an alternative embodiment, the cooling member is provided with two, and the two cooling members are symmetrically arranged about the center of the heating member, and the two cooling members are respectively arranged one-to-one with the gear teeth on both sides of the tooth groove to be machined.

[0026] Beneficial effects: The two cooling members are symmetrically arranged about the center of the heating member, and the two cooling members are one-to-one corresponding to the gear teeth on both sides of the tooth groove to be machined, which can ensure that the cooling effect of the gear teeth on both sides of the tooth groove to be machined is consistent. During heating, the gear teeth on both sides of the tooth groove to be machined are affected by similar heat, and the symmetrically arranged cooling members can cool the two gear teeth in the same way, avoiding the situation that one side is cooled too much while the other side is not cooled enough, ensuring the thermal balance of the meshing member as a whole, which helps to maintain the mechanical performance stability of the gear teeth.

[0027] In addition, before using the tooth surface heating and cooling device, only the two cooling members need to be adjusted to correspond to the gear teeth on both sides of the tooth groove to be machined, so as to adjust the correspondence between the cooling member and the gear teeth.

[0028] In an alternative embodiment, the bottom of the nozzle is provided with an adjusting bolt, the rack is provided with a mounting hole corresponding to the adjusting bolt, and the nozzle and the rack are adjustably arranged by penetrating the adjusting bolt into the mounting hole.

[0029] Beneficial effects: By adjusting the tightness of the adjusting bolt, the operator can conveniently adjust the position of the nozzle relative to the gear teeth. When facing meshing parts of different sizes, shapes or slight differences in installation position, the spray holes of the nozzle can be accurately aligned with the addendum and dedendum, ensuring that the cooling medium is optimally sprayed, achieving efficient cooling and improving the quality and consistency of the heat treatment of the meshing parts.

[0030] The connection mode of the adjusting bolt makes the installation and removal of the nozzle on the rack relatively simple. When the nozzle needs to be replaced or cleaned and repaired, the operator can quickly loosen the adjusting bolt, remove or adjust the nozzle without complex tools and cumbersome operation steps, reducing the operation steps, greatly reducing the difficulty and time cost of equipment maintenance, and improving the production efficiency and availability of the equipment.

[0031] In an optional embodiment, the heating member includes a first induction plate, a second induction plate, and a connecting rod. The first induction plate and the second induction plate are spaced apart along the height direction of the tooth surface heating and cooling device. The connecting rod is arranged at the end of the first induction plate and the second induction plate and communicates the first induction plate and the second induction plate, so that the current flows from the first induction plate to the connecting rod and then to the second induction plate, forming a current loop.

[0032] Beneficial effects: When the current flows from the first induction plate to the connecting rod and then to the second induction plate, forming a current loop, an alternating magnetic field is generated around the heating member. Since the first induction plate and the second induction plate are spaced apart along the height direction, a relatively uniform magnetic field can be generated within a certain height range of the tooth groove wall surface. When the tooth groove wall surface of the meshing part is in the alternating magnetic field, an induced current is generated inside the tooth groove wall surface. The induced current generates heat under the resistance of the tooth groove wall surface, thereby achieving heating of the tooth groove wall surface. The heating efficiency of this heating member is high, and the tooth groove wall surface can quickly reach the required temperature for quenching.

[0033] The spacing of the first induction plate and the second induction plate helps to expand the heating area. In the height direction, a certain length of the tooth groove wall surface can be covered, avoiding the situation of local overheating or insufficient heating. Compared with a single induction heating plate, the temperature distribution of the tooth groove wall surface in the height direction is more uniform, which is beneficial to improve the heat treatment quality of the tooth groove wall surface of the meshing part.

[0034] In an optional embodiment, the first induction plate and the second induction plate are both configured as a curved structure body that is adapted to the tooth groove wall surface.

[0035] Beneficial effects: When both the first and second induction plates are constructed as curved structures adapted to the tooth groove wall, placing the first and second induction plates in the tooth groove to be processed can maintain a suitable distance between the first and second induction plates and the tooth groove wall, making the heating of each heating area of ​​the tooth groove wall more uniform, and effectively avoiding insufficient or excessive heating at the edges or corners of the tooth groove wall.

[0036] In one optional embodiment, the heating element further includes a magnetic field concentrator, and an installation cavity is formed between the first induction plate, the second induction plate and the connecting rod, with the magnetic field concentrator disposed within the installation cavity.

[0037] Beneficial effects: Installing the magnetic field concentrator inside the mounting cavity can drive the magnetic field to be concentrated on the first induction plate, the second induction plate, and the connecting rod, thereby enhancing the magnetic field strength and improving heating efficiency.

[0038] Secondly, this utility model also provides a tooth surface heating and cooling system, comprising:

[0039] Tooth surface heating and cooling device;

[0040] A driving component, connected to the nozzle, is used to drive the nozzle to spray cooling medium;

[0041] A controller, electrically connected to the drive unit, adjusts the flow rate of the cooling medium sprayed from the nozzle by controlling the drive unit.

[0042] Beneficial effects: This tooth surface heating and cooling system can provide suitable cooling rates for the teeth depending on the material, size, and degree of heating required. By precisely controlling the drive components and adjusting the flow rate of the cooling medium in the nozzles, the system can provide appropriate cooling conditions for the teeth based on actual conditions.

[0043] Simultaneously, it enables automated control. Operators only need to set the corresponding parameters in the controller, and the system can automatically adjust the cooling medium flow rate, eliminating the need for manual adjustment of each nozzle. This not only reduces labor input but also ensures the stability and consistency of the entire production process. Attached Figure Description

[0049] In the field of mechanical manufacturing, gears and gear rings are key transmission components whose performance directly affects the operating efficiency and reliability of the entire mechanical equipment. Induction hardening is a heat treatment process widely used to improve the surface hardness and wear resistance of meshing parts. By rapidly heating and cooling the tooth surface of the meshing parts, a hardened layer is formed on the tooth surface, thereby improving the overall performance of the meshing parts.

[0050] When induction hardening meshing parts, a common method is to heat and cool each tooth individually. However, when the induction head heats the current tooth of the meshing part, the narrow width of a single tooth can easily cause heat to transfer to adjacent teeth, resulting in excessively high temperatures on those teeth and leading to over-tempering. Over-tempering reduces the surface hardness and durability of the meshing part's tooth surfaces, affecting its performance and service life.

[0051] To address this, this application attempted to use nozzles to spray cooling media onto adjacent gear teeth to prevent heat transfer to those teeth. First, the cooling media was sprayed onto the root of the adjacent teeth. Because the root of the teeth is relatively thick, it is less affected by temperature changes, thus the cooling media effectively cooled the root. However, because the tip of the teeth is relatively narrow, it is more affected by temperature changes, and spraying the cooling media only onto the root was insufficient to effectively reduce the temperature at the tip.

[0052] Therefore, this application attempts to accelerate the cooling rate by increasing the flow rate of the cooling medium, hoping to improve the cooling effect. However, although this method improves the cooling rate to some extent, the inability to precisely control the spray direction and coverage of the cooling medium leads to over-cooling in some areas and under-cooling in others. This not only fails to achieve uniform cooling but may also cause defects such as cracks and deformation due to excessive thermal stress, reducing the product's yield.

[0053] Based on this, this application provides multiple cooling elements on both sides of the sensing head. Nozzles on these cooling elements spray cooling medium onto the top and back surfaces of the gear teeth through spray holes. Alternatively, cooling medium can be sprayed only onto the top or back surfaces of the gear teeth, effectively reducing the temperature of adjacent gear teeth and preventing heat accumulation on them. This avoids excessive tempering caused by overheating. It ensures that the hardness and durability of the meshing parts' tooth surfaces meet requirements, improving the overall quality and performance of the meshing parts and extending their service life.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0055] To solve the above technical problems, the following will be combined with... Figures 1 to 2 The following describes embodiments of the present invention.

[0056] According to embodiments of the present invention, on the one hand, such as Figure 1 and Figure 2 As shown, a tooth surface heating and cooling device is provided for heating and cooling a meshing member 1. The meshing member 1 has a tooth groove 102 to be processed, and the tooth groove 102 has a tooth groove wall surface 1011. Two gear teeth 101 adjacent to the tooth groove 102 in the meshing member 1 have tooth back surfaces 1013 that are opposite to the tooth groove 102. The top surface of the gear teeth 101 is a tooth tip surface 1012.

[0057] Specifically, such as Figure 1 As shown, the tooth surface heating and cooling device includes a frame 2, a heating element 3, and multiple cooling elements 4.

[0058] Specifically, such as Figure 1 and Figure 2 As shown, the heating element 3 is mounted on the frame 2. The heating element 3 is adapted to be mounted inside the tooth groove 102 to be processed, and the tooth groove wall 1011 is heated by the heating element 3.

[0059] Specifically, such as Figure 1 and Figure 2As shown, multiple cooling elements 4 are adjustablely mounted on the frame 2, and the multiple cooling elements 4 are located on opposite sides of the heating element 3.

[0060] Specifically, such as Figure 1 and Figure 2 As shown, the cooling component 4 includes a nozzle 401, which has a spray hole 4011. The nozzle 401 sprays a cooling medium toward the tooth top surface 1012 and / or tooth back surface 1013 of the gear tooth 101 through the spray hole 4011.

[0061] This tooth surface heating and cooling device, when quenching and heating the meshing part 1, places the heating element 3 in a single tooth groove 102 of the meshing part 1 to be processed. The heating element 3 heats the tooth groove wall 1011 of the tooth 101, concentrating the heat on the tooth groove wall 1011 to be processed, reducing the heat transfer to adjacent teeth 101. At the same time, when the heating element 3 heats the current tooth groove wall 1011, the heat tends to diffuse to adjacent teeth 101. Since multiple cooling elements 4 are located on both sides of the heating element 3, the nozzles 401 on the cooling elements 4 spray cooling medium towards the tooth tip 1012 and tooth back 1013 of the tooth 101 through the spray holes 4011, or spray cooling medium only towards the tooth tip 1012 or tooth back 1013 of the tooth 101, effectively reducing the temperature of adjacent teeth 101, preventing heat from accumulating on adjacent teeth 101, and thus avoiding overheating caused by excessive temperature. Ensuring that the hardness and durability of the tooth surface of meshing component 1 meet the requirements improves the overall quality and performance of meshing component 1 and extends its service life.

[0062] Furthermore, since multiple cooling components 4 are adjustablely mounted on the frame 2, the cooling components 4 can adapt to meshing components 1 of different sizes and shapes. Operators can adjust the position or angle of the cooling components 4 according to the characteristics of the specific meshing component 1, so that the spray holes 4011 of the nozzle 401 can accurately spray the cooling medium onto the tooth top surface 1012 and / or the tooth back surface 1013, achieving uniform and effective cooling, avoiding soft spots or other defects on the tooth surface of the meshing component 1 due to uneven cooling, and further ensuring the heat treatment effect and reliability of the meshing component 1.

[0063] In summary, by heating and cooling the meshing component 1 using a tooth surface heating and cooling device, it is possible to effectively prevent the temperature of adjacent gear teeth 101 from becoming too high, thereby avoiding excessive tempering and improving the performance and service life of the meshing component 1.

[0064] Specifically, the frame 2 can be configured in any existing shape, such as a flat plate or a block. The frame 2 can be made of insulating material or insulating and high-temperature resistant material. In this embodiment, there are no specific limitations on the shape and material of the frame 2.

[0065] Specifically, the meshing component 1 can be a meshing component with multiple teeth 101, such as a gear ring or gear. In this embodiment, the type of meshing component 1 is not specifically limited.

[0066] Specifically, the heating element 3 can be selected from induction head, heating coil, resistance heating element, etc. In this embodiment, the type of heating element 3 is not specifically limited.

[0067] For example, when the heating element 3 is an induction head, the induction head can rapidly generate heat on the tooth groove wall 1011 using the principle of electromagnetic induction, achieving a fast and efficient heating process. The heating speed of the induction head is significantly improved compared to some traditional heating methods, greatly shortening processing time and increasing production efficiency. In terms of temperature control, the induction head can precisely control the heating temperature by adjusting parameters such as current magnitude and frequency, thereby meeting the heating temperature requirements of the tooth groove wall 1011 of the meshing part 1 under different material and process requirements, ensuring the quality of the meshing part 1.

[0068] Specifically, the cooling medium can be oil-based or water-based. In this embodiment, no specific restrictions are placed on the type of cooling medium.

[0069] Specifically, multiple cooling components 4 can be connected to the frame 2 via rotary joints, allowing the cooling components 4 to be adjustablely positioned on the frame 2. Alternatively, multiple cooling components 4 can be mounted on the frame 2 via bolt connections, allowing the cooling components 4 to be adjustablely positioned on the frame 2. In this embodiment, no specific limitations are placed on the connection method between the cooling components 4 and the frame 2.

[0070] Specifically, the multiple cooling elements 4 can be two cooling elements 4, three cooling elements 4, or four cooling elements 4, etc. The nozzle 401 of one cooling element 4 can correspond to one gear tooth 101, or the nozzle 401 of one cooling element 4 can correspond to multiple gear teeth 101. In the embodiments of this application, the number of cooling elements 4 and the correspondence between cooling elements 4 and gear teeth 101 are not specifically limited.

[0071] For example, the multiple cooling elements 4 can be four cooling elements 4, with two cooling elements 4 located on one side of the heating element 3 and the other two cooling elements 4 located on the other side of the heating element 3. One of the two cooling elements 4 can correspond to the tooth tip surface 1012 of the adjacent gear tooth 101, and the other cooling element 4 can correspond to the tooth back surface 1013 of the adjacent gear tooth 101, so that the two cooling elements 4 spray cooling medium onto the tooth tip surface 1012 and tooth back surface 1013 of the adjacent gear tooth 101 respectively, which can effectively reduce the temperature of the adjacent gear tooth 101.

[0072] Specifically, the nozzle 401 is provided with a plurality of spray holes 4011, which can be evenly distributed on the nozzle 401 or non-uniformly distributed on the nozzle 401. Taking the plurality of spray holes 4011 evenly distributed on the nozzle 401 as an example, it can be ensured that the cooling medium is evenly sprayed onto the tooth tip surface 1012 and / or tooth back surface 1013 of the gear tooth 101, ensuring uniform cooling of the tooth tip surface 1012 and / or tooth back surface 1013 of the gear tooth 101.

[0073] It should be noted that when nozzle 401 sprays cooling medium towards the tooth tip 1012 and / or tooth back 1013 of gear tooth 101 through spray hole 4011, it can be understood that nozzle 401 sprays cooling medium towards both the tooth tip 1012 and tooth back 1013 of gear tooth 101 through spray hole 4011, or it can be understood that nozzle 401 sprays cooling medium only towards the tooth tip 1012 of gear tooth 101 through spray hole 4011, or nozzle 401 sprays cooling medium only towards the tooth back 1013 of gear tooth 101 through spray hole 4011.

[0074] In one embodiment, such as Figure 1 and Figure 2 As shown, the nozzle 401 is provided with a first spray surface 4012 and a second spray surface 4013. The first spray surface 4012 is corresponding to the tooth tip surface 1012 of the gear tooth 101, and the second spray surface 4013 is corresponding to the tooth back surface 1013 of the gear tooth 101. The first spray surface 4012 and the second spray surface 4013 are set at an angle, and both the first spray surface 4012 and the second spray surface 4013 are provided with a plurality of spray holes 4011.

[0075] By providing a first spray surface 4012 and a second spray surface 4013 on the nozzle 401, and ensuring that the first spray surface 4012 and the second spray surface 4013 correspond to the tooth tip surface 1012 and the tooth back surface 1013 of the gear tooth 101 respectively, direct and comprehensive cooling of the two key parts of the gear tooth 101 can be ensured. While the heating element 3 heats the tooth groove 102 to be processed, the first spray surface 4012 and the second spray surface 4013 can simultaneously spray cooling medium onto the tooth tip surface 1012 and the tooth back surface 1013, thereby cooling the tooth tip surface 1012 and the tooth back surface 1013 at the top of the gear tooth 101, effectively reducing the temperature of adjacent gear teeth 101, preventing heat from accumulating on adjacent gear teeth 101, and thus ensuring that the tooth root to the tooth tip of the gear tooth 101 obtains the same hardness and strength.

[0076] Furthermore, the first spray surface 4012 and the second spray surface 4013 are set at an angle, which allows for a variety of spray directions for the cooling medium. Compared to spraying from a single plane, multi-angle spraying allows the cooling medium to better cover the tooth top surface 1012 and the tooth back surface 1013, reducing cooling dead zones, improving cooling uniformity, and helping to prevent problems such as tooth surface hardness differences and deformation caused by uneven cooling, thus ensuring the quality and performance stability of the meshing part 1.

[0077] Specifically, the angle between the first spray surface 4012 and the second spray surface 4013 is related to the shape of the gear tooth 101. In this embodiment, the angle between the first spray surface 4012 and the second spray surface 4013 is not specifically limited.

[0078] For example, the tooth tip surface 1012 and tooth back surface 1013 of the gear tooth 101 are usually set at an obtuse angle. The angle between the first spray surface 4012 and the second spray surface 4013 can be set to an obtuse angle so that the first spray surface 4012 and the second spray surface 4013 can accommodate more types of meshing parts 1.

[0079] Specifically, the spray holes 4011 on the first spray surface 4012 can spray cooling medium towards the entire tooth tip surface 1012 or towards a portion of the tooth tip surface 1012. Similarly, the second spray surface 4013 can spray cooling medium towards the entire tooth back surface 1013 or towards a portion of the tooth back surface 1013. In this embodiment, the spray area of ​​the first spray surface 4012 and the second spray surface 4013 is not specifically limited.

[0080] In one embodiment, such as Figure 2 As shown, the width of the first spray surface 4012 is b1, and the width of the tooth tip surface 1012 of the gear tooth 101 is b2, satisfying b1 < b2, so that the first spray surface 4012 sprays cooling medium toward the tooth tip surface 1012 and away from the tooth groove wall surface 1011.

[0081] Since the width b1 of the first spray surface 4012 is smaller than the width b2 of the tooth tip surface 1012, and the first spray surface 4012 sprays cooling medium toward the tooth tip surface 1012 away from the tooth groove wall 1011, the first spray surface 4012 can effectively reduce the temperature of the tooth tip surface 1012 when spraying cooling medium onto the tooth tip surface 1012. At the same time, it prevents the cooling medium from splashing onto the vicinity of the heated tooth groove wall 1011 during the spraying process, thereby reducing the heating temperature of the tooth groove wall 1011 and causing a decrease in the hardness of the tooth groove wall 1011.

[0082] During the heating process, the tooth groove wall 1011 needs to reach a certain temperature to achieve effective quenching of the gear teeth 101. If the cooling medium affects the tooth groove wall 1011 too much, it will interfere with the heating effect, resulting in uneven heating or failure to reach the expected quenching temperature.

[0083] Specifically, the direction in which the cooling medium is sprayed from the first spray surface 4012 can be perpendicular to the tooth top surface 1012, and the direction in which the cooling medium is sprayed from the first spray surface 4012 can also be tilted so that the cooling medium is tilted toward the side away from the tooth groove wall 1011, thereby preventing the cooling medium from flowing toward the tooth groove wall 1011 during the spraying process.

[0084] In one embodiment, such as Figure 1 As shown, along the height direction of the tooth surface heating and cooling device, the height of the nozzle 401 is greater than or equal to 2 / 3 of the height of the heating element 3.

[0085] The height of nozzle 401 is greater than or equal to 2 / 3 of the height of heating element 3, allowing the cooling medium to cool the gear teeth 101 over a wider height range. During the heating process, due to the influence of the height of heating element 3, heat will be transferred and accumulated at different height positions of gear teeth 101. The higher nozzle 401 ensures that the cooling medium covers more heated areas, effectively reducing the temperature of various parts of gear teeth 101. In particular, it has a positive effect on heat dissipation at higher positions on the tooth top surface 1012 and tooth back surface 1013, preventing problems such as excessive tempering or uneven hardness caused by local high temperature, thereby improving the overall heat treatment quality of meshing parts 1.

[0086] If the height of nozzle 401 is less than 2 / 3 of the height of heating element 3, heat will be transferred and accumulated in various parts of gear tooth 101 during the heating process due to the influence of the height of heating element 3. Because the nozzle 401 is too small, the cooling medium cannot effectively cover a large area of ​​gear tooth 101, resulting in insufficient heat dissipation in some areas of gear tooth 101. This may cause uneven hardness at different heights of gear tooth 101, affecting the overall mechanical properties and service life of meshing component 1.

[0087] For example, in order to ensure that the nozzle 401 can cool the heated area of ​​the gear tooth 101 in a timely manner, the height of the nozzle 401 can be set to be greater than the height of the heating element 3.

[0088] In one embodiment, such as Figure 1 and Figure 2 As shown, the cooling component 4 also includes a connecting pipe 402, wherein the nozzle 401 is provided with a pipe connector 4014 communicating with the spray hole 4011, and the nozzle 401 is connected to the connecting pipe 402 through the pipe connector 4014.

[0089] By connecting the connecting pipe 402 to the nozzle 401, the connecting pipe 402 provides a stable transmission channel for the cooling medium, which can continuously deliver the cooling medium from the outside to the nozzle 401 and spray it out from the spray hole 4011 of the nozzle 401.

[0090] Since the nozzle 401 is provided with a pipe joint 4014, the nozzle 401 is connected to the connecting pipe 402 through the pipe joint 4014, so that the connecting pipe 402 can be connected to the nozzle 401. At the same time, it ensures that the cooling medium flows smoothly during the delivery to the nozzle 401, avoiding problems such as leakage, so that the cooling component 4 can continuously and effectively cool the gear tooth 101.

[0091] When nozzle 401 becomes clogged, damaged, or requires replacement with a different type of nozzle 401 to meet different cooling needs, the connection method of pipe fitting 4014 makes the disassembly and installation of nozzle 401 relatively simple. Operators can quickly detach the old nozzle 401 from the connecting pipe 402 and install the new nozzle 401, reducing maintenance costs and time.

[0092] Specifically, one end of the connecting pipe 402 can be inserted into the pipe fitting 4014, and the connecting pipe 402 and the pipe fitting 4014 are interference-fitted to ensure a firm connection. Alternatively, the connecting pipe 402 and the pipe fitting 4014 can also be detachably connected by a clamp. In this embodiment, no specific restrictions are placed on the connection method between the connecting pipe 402 and the pipe fitting 4014.

[0093] Specifically, the connecting pipe 402 can be a rigid pipe or a flexible pipe, and the pipe fitting 4014 can be a threaded pipe fitting or a quick-connect pipe fitting. In this embodiment, the types of the connecting pipe 402 and the pipe fitting 4014 are not specifically limited.

[0094] In one embodiment, such as Figure 1 and Figure 2 As shown, there are two cooling components 4, which are symmetrically arranged about the center plane of the heating component 3, and the two cooling components 4 are respectively arranged in a one-to-one correspondence with the gear teeth 101 on both sides of the gear groove 102 to be processed.

[0095] The two cooling elements 4 are symmetrical about the center plane of the heating element 3, and each cooling element 4 corresponds one-to-one with the gear teeth 101 on both sides of the gear groove 102 to be processed, ensuring that the cooling effect of the gear teeth 101 on both sides of the gear groove 102 to be processed is consistent. During the heating process, the gear teeth 101 on both sides of the gear groove 102 to be processed are affected by heat in a similar way. The symmetrically arranged cooling elements 4 can cool the two gear teeth 101 in the same way, avoiding the situation where one side is over-cooled and the other side is under-cooled, ensuring the overall thermal balance of the meshing element 1, and helping to maintain the stability of the mechanical properties of the gear teeth 101.

[0096] In addition, before using the tooth surface heating and cooling device, it is only necessary to adjust the two cooling components 4 to correspond one-to-one with the gear teeth 101 on both sides of the tooth groove 102 to be processed, so as to adjust the correspondence between the cooling components 4 and the gear teeth 101.

[0097] In one embodiment, such as Figure 1 As shown, the nozzle 401 has an adjusting bolt 403 at its bottom, and the frame 2 has a mounting hole 201 corresponding to the adjusting bolt 403. The nozzle 401 and the frame 2 can be adjusted by the adjusting bolt 403 passing through the mounting hole 201.

[0098] By adjusting the tightness of the adjusting bolt 403, the operator can easily adjust the position of the nozzle 401 relative to the gear tooth 101. When dealing with meshing parts 1 that have slight differences in size, shape, or installation position, the spray hole 4011 of the nozzle 401 can be precisely aligned with the tooth top surface 1012 and the tooth back surface 1013 to ensure the best spraying effect of the cooling medium, achieve efficient cooling, and improve the quality and consistency of the heat treatment of the meshing parts 1.

[0099] The connection method of the adjusting bolt 403 makes the installation and removal of the nozzle 401 on the frame 2 relatively simple. When it is necessary to replace the nozzle 401 or to clean or maintain it, the operator can quickly loosen the adjusting bolt 403, remove or adjust the nozzle 401 without complicated tools and cumbersome operating procedures. The reduced operating procedures reduce the difficulty and time cost of equipment maintenance, and improve production efficiency and equipment availability.

[0100] Specifically, multiple mounting holes 201 can be provided on the frame 2. When adjusting the position of the nozzle 401, the adjusting bolt 403 can be inserted into the appropriate mounting hole 201 so that the spray hole 4011 of the nozzle 401 is aligned with the tooth top surface 1012 and the tooth back surface 1013. Alternatively, a single mounting hole 201 can be provided on the frame 2. When the position of the nozzle 401 needs to be adjusted, simply loosen the adjusting bolt 403. At this time, the nozzle 401 can rotate on the frame 2. When the spray hole 4011 of the nozzle 401 is rotated to align with the tooth top surface 1012 and the tooth back surface 1013, the position of the nozzle 401 can be fixed by tightening the adjusting bolt 403.

[0101] In one embodiment, such as Figure 1 and Figure 2 As shown, the heating element 3 includes a first induction plate 301, a second induction plate 302, and a connecting rod 303. The first induction plate 301 and the second induction plate 302 are spaced apart along the height direction of the induction heating and cooling device. The connecting rod 303 is disposed at the ends of the first induction plate 301 and the second induction plate 302, and the connecting rod 303 connects the first induction plate 301 and the second induction plate 302, so that current flows from the first induction plate 301 to the connecting rod 303 and then to the second induction plate 302 to form a current loop.

[0102] When current flows from the first induction plate 301 to the connecting rod 303 and then through the connecting rod 303 to the second induction plate 302 to form a current loop, an alternating magnetic field is generated around the heating element 3. Since the first induction plate 301 and the second induction plate 302 are spaced apart along the height direction, a relatively uniform magnetic field can be generated within a certain height range of the tooth groove wall 1011. When the tooth groove wall 1011 of the meshing element 1 is in the alternating magnetic field, an induced current is generated inside the tooth groove wall 1011. This induced current generates heat under the resistance of the tooth groove wall 1011, thereby heating the tooth groove wall 1011. This heating element 3 has high heating efficiency and can quickly bring the tooth groove wall 1011 to the temperature required for quenching.

[0103] The spacing between the first induction plate 301 and the second induction plate 302 helps to expand the heating area. In the height direction, it can cover a certain length of the tooth groove wall 1011, avoiding local overheating or underheating. Compared with a single induction heating plate, it can make the temperature distribution of the tooth groove wall 1011 in the height direction more uniform, which is beneficial to improving the heat treatment quality of the tooth groove wall 1011 of the meshing part 1.

[0104] Specifically, the first sensing plate 301, the second sensing plate 302, and the connecting rod 303 can be made of copper. In this embodiment, no specific restrictions are placed on the materials of the first sensing plate 301, the second sensing plate 302, and the connecting rod 303.

[0105] For example, when the first induction plate 301, the second induction plate 302, and the connecting rod 303 are all made of copper, the heating element 3 has extremely high conductivity, which effectively reduces current loss during transmission and ensures a stable current loop during induction heating, thereby generating a stable alternating magnetic field and improving heating efficiency and uniformity. During induction heating, the heating element 3 can quickly conduct heat, avoiding local overheating and helping to extend the service life of the heating element 3.

[0106] Specifically, the first sensing plate 301 and the second sensing plate 302 can be arranged in parallel or in a non-parallel manner. In this embodiment, no specific restrictions are placed on the arrangement of the first sensing plate 301 and the second sensing plate 302.

[0107] Specifically, the first sensing plate 301 and the second sensing plate 302 can be configured to have similar shapes or different shapes. In this embodiment, the shape and structure of the first sensing plate 301 and the second sensing plate 302 are not specifically limited.

[0108] Specifically, such as Figure 1 and Figure 2 As shown, a connector 5 can be installed on the heating element 3, and the heating element 3 is mounted on the frame 2 through the connector 5. At the same time, the heating element 3 can also be electrically connected to an external busbar interface through the connector 5.

[0109] In one embodiment, combined Figure 1 and Figure 2 As shown, both the first sensing plate 301 and the second sensing plate 302 are constructed as curved structures, and the curved structures are adapted to the tooth groove wall 1011.

[0110] When both the first sensing plate 301 and the second sensing plate 302 are constructed as curved structures adapted to the tooth groove wall 1011, placing the first sensing plate 301 and the second sensing plate 302 inside the tooth groove 102 to be processed can maintain a suitable distance between the first sensing plate 301 and the second sensing plate 302 and the tooth groove wall 1011, making the heating of each heating area of ​​the tooth groove wall 1011 more uniform, and effectively avoiding insufficient or excessive heating at the edges or corners of the tooth groove wall 1011.

[0111] Specifically, when the heating element 3 is placed inside the tooth groove 102 to be processed, the distance between the first induction plate 301 and the second induction plate 302 and the tooth groove wall 1011 can be set to 1mm-2mm to ensure that the heating element 3 is inductively compatible and can reasonably heat the tooth groove wall 1011. If the distance is too large, the heating speed of the heating element 3 will be slow and the heating efficiency will be low. If the distance is too small, the heating element 3 may come into contact with the tooth groove wall 1011, which may cause a short circuit risk.

[0112] In one embodiment, such as Figure 1 As shown, the heating element 3 also includes a magnetic field concentrator. An installation cavity 304 is formed between the first induction plate 301, the second induction plate 302 and the connecting rod 303, and the magnetic field concentrator is disposed in the installation cavity 304.

[0113] Installing the magnetic field concentrator inside the mounting cavity 304 can drive the magnetic field to be concentrated on the first induction plate 301, the second induction plate 302 and the connecting rod 303, thereby enhancing the magnetic field strength and improving the heating efficiency.

[0114] Specifically, the magnetic field concentrator can be made of silicon steel sheets, etc. In this embodiment, no specific restrictions are placed on the type of magnetic field concentrator.

[0115] According to an embodiment of the present invention, another aspect provides a tooth surface heating and cooling system, including a tooth surface heating and cooling device, a drive component, and a controller.

[0116] Specifically, the drive unit (not shown in the figure) is connected to the nozzle 401, and the drive unit is used to drive the nozzle 401 to spray the cooling medium.

[0117] Specifically, the controller (not shown in the figure) is electrically connected to the drive unit, and the controller adjusts the flow rate of the cooling medium sprayed by the nozzle 401 through the drive unit.

[0118] This tooth surface heating and cooling system may require different cooling rates depending on the material, size, and degree of heating of the gear teeth 101 during operation. By precisely controlling the drive components through the controller, the flow rate of the cooling medium in the nozzle 401 can be adjusted, providing suitable cooling conditions for the gear teeth 101 according to the actual situation.

[0119] Simultaneously, it enables automated control. Operators only need to set the corresponding parameters in the controller, and the system can automatically adjust the cooling medium flow rate, eliminating the need for manual adjustment of each nozzle 401. This not only reduces labor input but also ensures the stability and consistency of the entire production process.

[0120] Specifically, the driving component can be an existing driving mechanism such as an oil pump or an electric pump. In this embodiment, no specific restrictions are placed on the type of driving component.

[0121] Specifically, the tooth surface heating and cooling system also includes a detection unit, which can be used to detect parameters such as the tooth surface hardness of the meshing component 1. The controller can control the drive component to adjust the cooling medium flow rate based on the detection parameters of the detection unit. The controller can also adjust the cooling medium flow rate based on the operator's experience.

[0122] The working principle of the tooth surface heating and cooling system in this embodiment is described as follows:

[0123] For ease of understanding, oil is used as the cooling medium, and the meshing part 1 is immersed in oil for quenching and hardening.

[0124] First, immerse the entire meshing component 1 in oil. Place the heating element 3 inside the tooth groove 102 to be processed, ensuring that the distance between the heating element 3 and the tooth groove wall 1011 is 1mm-2mm. Then, adjust the position of the nozzle 401 so that the first spray surface 4012 of the nozzle 401 is aligned with the tooth top surface 1012 and the second spray surface 4013 is aligned with the tooth back surface 1013, ensuring that the distance between the nozzle 401 and the tooth 101 is 1mm-3mm.

[0125] Since the heating element 3 includes a first induction plate 301, a second induction plate 302, and a connecting rod 303, current flows sequentially through the first induction plate 301, the connecting rod 303, and the second induction plate 302 to form a current loop, generating an alternating magnetic field around the heating element 3, thereby heating the tooth groove wall 1011. During the heating process, steam is locally generated in the heating element 3, which discharges the oil in the tooth groove 102 to be processed, thus heating the tooth groove wall 1011.

[0126] Since the drive unit is connected to the nozzle 401, the drive unit works under the control of the controller, delivering oil to the nozzle 401 through the connecting pipe 402. When the oil is sprayed out through the spray holes 4011 of the first spray surface 4012 and the second spray surface 4013, it will directly act on the tooth tip surface 1012 and tooth back surface 1013 of the gear tooth 101, carrying away heat, effectively reducing the temperature of adjacent gear teeth 101, preventing heat from accumulating on adjacent gear teeth 101, so that the gear tooth 101 obtains the same hardness and strength from the tooth root to the tooth tip.

[0127] Since the controller is electrically connected to the drive unit, the operator can control the drive unit through the controller to adjust the flow rate of the oil injected by the nozzle 401, and provide suitable cooling conditions for the gear 101 according to the actual situation.
